Hyperlipidemia is an elevation of lipids (fats) in the blood. These lipids include cholesterol, cholesterol esters (compounds), phospholipids and triglycerides, and are named hypercholesterolemia and hypertriglyceridemia in diagnosis. These large molecules are transported in the blood in the form of lipoproteins.

Actually, there are five kinds of lipoproteins in the blood:chylomicrons,very low-density,lipoproteins (VLDL),intermediate-density lipoproteins (IDL),low-density lipoproteins (LDL),and high-density lipoproteins (HDL), of which only HDL is beneficial for people.

Hyperlipidemia usually do not have unique symptoms and could only be found out with blood test. However, longterm hyperlipidemia would lead to various of discomforts.Deposits of cholesterol (known as xanthomas) may form under the skin (especially around the eyes or along the Achilles tendon). Individuals with hypertriglyceridemia may develop numerous pimple-like lesions across their body. Extremely high levels of triglycerides may also result in pancreatitis.High lipid levels can also speed up a process called atherosclerosis(hardening of the arteries). Your arteries are normally smooth and unobstructed on the inside surface, but as you age, a sticky substance called plaque forms in the walls of your arteries. Plaque is made of lipids and other materials in your blood. As more plaque builds up, your arteries become narrower and stiffener. Eventually, enough plaque may lead to reduction of blood flow through your arteries.......Sounds terrible, isn't it?

How could people ignore such a terrible disease? We'll talk about how to fight against it next.
